Important Aquarium Care Note
Fish stress can be caused by transport, netting, aggression, poor water quality, unstable temperature, ammonia or nitrite, disease, injury, or sudden environmental changes. StressGuard may be used as part of a fish-care routine, but the underlying cause should still be identified and corrected.
StressGuard does not replace water testing, proper acclimation, quarantine, filtration, water changes, or medication when treatment is needed.
